## How do you find the probability of two dice?

If you want to know how likely it is to get a certain total score from rolling two or more dice, it’s best to fall back on the simple rule: **Probability = Number of desired outcomes ÷ Number of possible outcomes.**

## When two dice are rolled find the probability of getting a sum of 12?

Probabilities for the two dice

10 | 3 | 8.33% |

11 | 2 | 5.56% |

12 | 1 |
2.78% |

Total | 36 | 100% |

## What is the probability of getting a sum?

Answer: The probability of rolling two dice and getting a sum of 4 is **1/12**. Let’s find how likely we get a sum of 4 when we roll two dice simultaneously. So, when we roll two dice there are 6 × 6 = 36 possibilities. When we roll two dice, the possibility of getting number 4 is (1, 3), (2, 2), and (3, 1).

## What is the probability that if we roll 2 dice the sum is 7?

For each of the possible outcomes add the numbers on the two dice and count how many times this sum is 7. If you do so you will find that the sum is 7 for 6 of the possible outcomes. Thus the sum is a 7 in 6 of the 36 outcomes and hence the probability of rolling a 7 is **6/36 = 1/6**.

## What is the probability of getting the sum of 4?

Probability of getting a sum of 4 on one toss of two dice is **3/36**, or 1/12.
